Title: Method for solidifying waste containing radioactive iodine
Inventor: FUKUMOTO MASAHIRO
IPC: G21F9/02
Filed: 1997-07-14
Abstract: A method for solidifying a radioactive iodine-containing waste, in which volatilization of radioactive iodine outward can  be suppressed during solidification, and  a  solidified waste  having  a high level of  confinement  of radioactive iodine  and  a  long term stability can  be  obtained.   The method   comprised   mixing  a  granular  waste   containing radioactive iodine, e.g. a granular iodine adsorbent  having radioactive  iodine adsorbed and collected thereon,  with  a metal  powder,  e.g.  a copper powder,  having  a  corrosion resistance  in an environment of solidified waste  disposal, filling  the  resulting  mixture in  a  metal  capsule,  and subjecting  the  whole to hot isostatic pressing  to  effect solidification.    In   the  resulting   solidified   waste, particles  of the radioactive  iodine-containing  adsorbents are  dispersed  and retained in the sintered matrix  of  the metal powder formed through the isostatic pressing.

Filed: 1996-01-12
Abstract: The needle loom comprises a support (1) and a stripper (2) defining the travel path for a sheet of fibres (3). A needle board (7) supported by sliding rods (11) effects a to-and-fro movement between the position of maximum penetration shown and a position of withdrawal, by means of two excentric rod devices each comprising a rod (19) articulated to the sliding rod (11). Each pair of rods is articulated to a crankshaft (23) supported by bearings (34) and fitted with balancing mechanisms. The bearings are supported by partitions (39) axially positioned between the excentrics (22) and the balancing mechanisms (27). The crankshaft (23) comes out of the case through simple shaft seals (36). Used to render the case more rigid and reduce the deformations allowed the crankshaft, in order to increase the punch rate.
Patent CA-2216080-A1 (CA)
Title: Transmission of voice over an asynchronous network
Inventor: TRUMBULL DEAN A
IPC: H04L12/16
Filed: 1997-09-22
Abstract: An SCSA RX/TX memory (220) receives voice data and stores voice data samples under established voice channel identifiers. A controller (240) selects voice channels, and their associated voice data, for inclusion in an ATM cell. The memory (220) sends the voice channel identifier and the voice data for the selected channels to a Constant Bit Rate Segmentation And Reassembly (CBR SAR) circuit (225). The CBR SAR aggregates the voice data into an appropriate number of ATM cell slots for each of those voice channels. The CBR SAR 225 sends the aggregated information to a Multiplexer/Duplicator Circuit (MUX/DUP) (230) which assembles the ATM cell, and sends the completed ATM cell to an ATM transceiver (265) for transmission. When there is no voice data to be sent information data from an Available Bit Rate (ABR) SAR (260) is assembled to form an ATM cell to be sent by the ATM transceiver. The MUX/DUP also receives an ATM cell from the ATM transceiver, duplicates the ATM cell, sends one copy of the ATM cell to the CBR SAR, and one copy of the ATM cell to the ABR SAR. The SARs disassemble the ATM cell, verify the channel identifiers, and route any valid channel identifiers and associated data to their respective memories. The SCSA memory attaches a channel identifier number to each voice data sample and sends the combination to the SCSA interface, which then places the combination on the SCSA port (210). A host device causes the information data to be read from the DATA memory via PCI ports (245) via a DMA operation.

Title: Integral flash steam generator
Inventor: ZELINA FRANCIS
IPC: F22B1/28
Filed: 1996-05-28
Abstract: The present invention is a flash steam generator to be used as an integral component of a steam sterilizer. The generator comprises a metal block (11) having a first bore (12) drilled lengthwise through the metal block. Surrounding the first bore is a plurality of additional heater bores (14) in which heating elements (15) are inserted. The generator is integral to the sterilizer piping and control systems. Water is supplied to the first bore (12) by the sterilizer piping system, and electricity is supplied to the heating elements by the sterilizer power supply. The heating elements (15) convert the electricity to heat, which transfers via the metal block (11) to the first bore (12) where the heat rapidly boils the water contained therein in what is essentially a flash vaporization process. An overtemperature device protects the system should the heaters be energized without sufficient water in the block. A safety valve exists between the block and the sterilizer chamber to protect the block and the chamber from overpressure conditions. The block and piping are properly insulated to prevent heat loss to the atmosphere and injury to persons operating the sterilizer.

Title: Optical source with monitor
Inventor: WIDMAN MICHAEL
IPC: G11B7/125
Filed: 1998-06-23
Abstract: An optical emission device includes a laser source having an emitting surface, and a sensor laterally adjacent the laser source generating an output signal dependent on the amount of light falling on its detection surface. A transparent waveguide is located in front of the emitting surface and extends generally parallel thereto such that light striking the waveguide in a direction normal to the emitting surface passes straight through the waveguide. A coupling medium is placed between the emitting surface and the waveguide. A light dispersant in the coupling medium causes a fraction of the laser light to strike the waveguide at an oblique angle so that it can enter the waveguide and be carried thereby to the sensor. An important advantage of the invention is that is uses inexpensive passive parts. The assembly process easy to implement, and the parts are stable during temperature changes. As a result only a small tracking error occurs.

Abstract: In a tub and shower unit, a faucet body 30 facilitates the supply of hot water and cold water either to a tub or a shower head, depending on whether a diverter valve of the unit is set in a tub mode or a shower mode.  A reversible ejector tee 82 or 138 is designed for assembly with a center body 84 of the faucet body 30 to insure that hot water and cold water, which is being supplied to the faucet body, will be directed to a spout of the tub when in a tub mode without any water leaking through the shower head.  The tee 82 or 138 will facilitate the directing of the water to the shower head when the diverter valve is in a shower mode.  The tee 82 or 138 can be reversed in its installed position within the center body 84 to accommodate different orientations of the faucet body 30.

IPC: E21B29/06
Filed: 1998-10-06
Abstract: Method and apparatus for producing fluids from a production zone(s) by drilling and completing multiple laterals from a primary wellbore. One or more pre-formed window units are provided in a casing string before it is cemented in the well. Each unit is comprised of a housing having an inlet and two outlets, one of which forms the pre-formed window. The axes of the two outlets forms a relatively small angle (e.g. 1' to 10', preferably 3°) whereby a well string will follow a gently curved path as it exits through the window. A re-entry line from the surface can be attached to the housing so that a work-over string can be lowered into a selective lateral without having to shut-in production from the other laterals.

Title: Method and apparatus for spacecraft amplification of multi-channel signals
Inventor: NORIN JOHN L
IPC: H04B7/185
Filed: 1998-10-19
Abstract: The number of high power amplifiers required for multi-channel satellite communications is reduced by a high power amplification of selected sets of signals in respec-tive common amplifiers, with each set of combined signals consisting of channels whose frequency bands are mutually discrete and sufficiently separated in frequency that their third order intermodulation products do not substantially overlap in frequency with any of the channels in the same set. The signals can be separated out again after amplification and transmitted as downlink signals, either individually from a dedicated downlink antenna or in combination with other channels in a common downlink antenna.
